Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31551134, here are decompositions:

37 + 31551097 = 31551134
67 + 31551067 = 31551134
157 + 31550977 = 31551134
211 + 31550923 = 31551134
283 + 31550851 = 31551134
331 + 31550803 = 31551134
337 + 31550797 = 31551134
463 + 31550671 = 31551134

Showing the first eight; more decompositions exist.
